So first off its around the time i should be starting my period. So this could seem unclear, but for the past week or so i've been really nauseas is only at night i throw up for at least 10 min but the feeling is still there well after. my breast are not sore but they are numb to the touch i still haven't started my period, and i keep smelling this one distinct smell that no one else seems to notice. there has been no sign of implantation bleeding but statisics so 64% of women wont show signs of that im tired all the time and dizzy i felt crampy for a few days.... SHOULD I BE WORRIED
